Prescribed for kidney stones and was sent home to pass stone. Slept 3 hours without pain and passed the stone some time later. Took for 2 more days due to pain from stone. Works excellent for relieving pain. Quit taking 2 days ago, as I was experiencing mild paranoia and mood swings, accompanied by heart palpations. Have drank a lot of liquids and performed mild exercising, but effects of the pills have continued, although not as severe. Be very very careful using this medication, and I would suggest only taking if absolutely necessary. Discontinue use asap after pain is manageable.
